Im planning on building a permanent duck blind for a decent sized swamp that i hunt, we own half of the shoreline and we do not know who owns the other shoreline. im planning on recording the wind and temperature and where on the swamp i hunt all 2013 fall waterfowl season so i know where to put it. all i was to know is how i should build it, im planning on having any where from 1-3 shooters and one dog. I have an idea of how big i want it, i was thinking about 6x8 or 6x9 with the door in the back but i dont know how to place it in the swamp, i want it water level so its in the cat tails. i would like to see some examples or plans to build one. anything will help I'm planning to build it over the winter after season and use it as a project for my agriculture class. Thanks!!
